PHOTOGRAPHIC RETOUCHER.

SPEGIFIGATION formingpart of Letters Patent No. 509,721, dated November28, 1893.

' Application filed June 30, 1893. Serial No. 479.233. (N0 model.)

To all whom it may concern:

Be it known that I, J AMEsRILEY DAKE, of Medford, in the county ofTaylor and State of Wisconsin, have invented a new and usefulRetouching-Machine, of which the following is a full, clear, and exactdescription.

My invention relates to a retouching machine, and it has for its objectto provide such a machine which will be exceedingly simple, durable andeconomic, and which may be conveniently used by any operator,saidmachine being capable of softening a line, stopping a pin hole,raising a shadow, sharpening an eye,

or raising a light in the eye or in the drapery,

as well as it can be accomplished by hand and in a far more expeditiousmanner.

A further object of the invention is to provide a retouching machinecapable of being driven by compressed air or an equivalent factor.

Theinventionconsists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claim.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures ofreference indicatecorresponding parts in all the views.

Figure 1 is a central longitudinal section through the machine. Fig.2 isasimilar section taken at a right angle to the section shown in Fig. 1,and essentially on the line 2-2 of Fig. 1. Fig. 3 is a transversesection taken at or about the center of the machine, practically on theline 3-3 of Fig. 2; and Fig. 4 is a transverse section taken essentiallyon the line 4-4 of Fig. 2, illustrating the driving mechanism of themachine in substantially plan view.

In carrying out the invention the body of the device consists of a tube10 of any desired material, and upon one side of the tube a casing 11,preferably of a circular formation is located, the casing being closedat its periphery and at its back or outer face; usually the face of thecasing opposite the tube is open, but it may be closed to a greater orless extent if in practice it is found advisable. Within the tube 10 apencil holder 12 is located, and the said pencil holder is ofconsiderably less diameter than the diameter of the tube or casing. Thepencil holder may be made tubular or solid, and extends at one end belowthe lower end of the casing, the lower extremity of the pencil holderbeing provided with a chuck 13 of any well known form, capable ofgripping and holding in position a lead or crayon 14, or a portion of alead pencil, as shown in Figs. 1 and 2. The pencil holder does not.usually extend to the top of the casing, and the upper end of thecasing is closed, as shown in Figs. 1 and 2. The pencil holder ispivotally located within the casing, being adapted to vibrate orlaterally reoiprocate therein, and the pivot point of the pencil holderis at a point about midway between its ends.

In order that the pencil holder may be rendered as sensitive as possibleto the action of the driving mechanism, the holder is provided inopposite sides with conical or angular cavities or recesses 15, as shownbest in Fig. 3; and the conical ends of set screws 16, are made to enterthese recesses, the said screws being held to turn in the casing, asshown in Figs. 2, 3 and 4, whereby any lost motion may be readily takenup when occasion may demand. The pencil holder is normally held againstone side wall of the easing at the lower end of the latter, as shown indot-ted lines in Fig. 1, through the medium of a spring 17. This springis usually attached to the upper portion of the casing, and extendslongitudinally along the exterior of the casing, the free end of thespring entering an aperture 18 in the casing, and it engages with thepencil holder below its pivot point, as is clearly shown in Fig. 1. Thespring may be made to exert more or less tension upon the pencil holder,and thereby hold it more or less firmly against the side of the casingwith which it is to contact through the medium of the set screw 19,which has bearing upon the upper portion of the spring, and the saidscrew is usually carried on the easing, or a bracket 20 secured to thelatter.

A lateral vibratory movement is imparted to the pencil holder throughthe medium of a shaft 21 and a wind wheel 22, the wind wheel beingsecured upon the shaft. The

shaft is conical at its ends, as shown. at 23 in Fig. 4, and one end ofthe shaft is journaled in a conical recess formed in the inner end of aset screw 25 located at the center of the casing 11, while the oppositeend of the shaft is journaled in like manner in a conical recess formedin a second set screw 26, located in the body tube 10, diametricallyopposite the set screw 25. Thus the shaft 21, is transversely locatedwithin the casing, and extends across its wider portion, and any lostmotion may be taken up by adjusting the screws 25 and 26. The wind wheel22, is rotated within the casing 11, through the medium of compressedair, or an equivalent agent introduced in the casing through an inlet27, as shown in Fig. 1, the inlet being so located that the air uponentering the casing will strike fairly upon the paddles of the wheel.Movement is imparted to the pencil holder through the medium of theshaft by causing the cylindrical surface of the shaft to engage with theupper portion of the pencil holder 12, as shown best in Figs. 1 and 4,the said holder being ordinarily provided at its point of contact withthe shaft with an extension 28. \Vhere the shaft strikes the pencilholder it is provided in one side with a recess 29, and in operation, asthe wind wheel is turned and the shaft is rotated, when the cylindricalportion of the shaft engages with the pencil holder it will force it indirection of one side of the casing at its upper end, as shown inpositive lines, Fig. 1, the pencil point being carried in contact withthe opposite side of the body at the lower-end thereof; and at this timethe spring 17 is placed under tension; therefore, as soon as theshaftrevolves sufficiently :to bring its recess 29 opposite the pencilholder, the spring will reverse the position of the ends of the holder,restoring it to its normal position, as shown in Fig. 1, and thus by therapid alternate action of the driving shaft 21 and the spring .17 uponthe pencil holder, the latter is kept in constant vibration, and thepencil, when employed for retouching will produce such a stroke as isproduced by hand, and the work which it will perform will be quite assatisfactory and may be executed in a much more expeditious manner. Thelength of the stroke of the pencil holder is limited by placing theadjusting screw 30 in the body tube preferably near its lower end andupon that side against which the said pencil holder is pressed by thespring 17.

It will be understood that the position of the spring 17 may be changed,as for example it may be made to work on the rear under side of thepencil holder and inside of the tube 10. A stop cock may also be placedin the air supply tube, and a guide of any desired character is placedat the front or rear of the pencil holder to take up side motion of thepencil.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A retoucher consisting in the tubular body or handpiece provided between its ends with an opening 18 and having a circularcase at its upper end, the vibratory pencil holder pivoted between itsends within the body, a pneu matic wheel within the casing with itsshaft or axle crossing the upper end of the holder and provided with acam or eccentric portion engaging said holder to move itin onedirection, a bracket on the upper end of the holder and provided with aset screw, a spring secured at one end beneath the bracket and extendingthence under the set screw and through the opening 18 into engagementwith the holder below its axis, substantially asset forth.
